    ****************************************************************
    WebSphere Application Server v8.5 includes version 3.2
    and version 4.0 of the ASM bytecode scanning library. The
    GenPluginCfg utility does not use OSGi internally and is unable
    to enforce bundle versioning. Because of incompatibilities
    between the two libraries, GenPluginCfg may throw an
    IncompatibleClassChangeError when processing Java Enterprise
    Edition 5 or 6 applications:
    java.lang.IncompatibleClassChangeError:
    org.objectweb.asm.ClassVisitor
    at java.lang.ClassLoader.defineClassImpl(Native Method)
    at java.lang.ClassLoader.defineClass(ClassLoader.java:262)
    

Problem conclusion

  • The scripts for GenPluginCfg utility were updated to ensure
    the correct ASM binary is first on the classpath.
    
    The following files were updated:
    
    For Microsoft Windows operating systems:
    * INSTALL_ROOT/bin/GenPluginCfg.bat
    For all other operating systems:
    * INSTALL_ROOT/bin/GenPluginCfg.sh
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.1.  Please refer to the Recommended Updates
